yes very true, lol its ok i foubnd out the hard way too...In order to scan ID's the radio has to have some in it when it scans whichever trunked system u have in, then instead of scanning freq, you can have it just scan Id's that it has picked up along the way...Hopefully this makes sense to ya, not sure as to how to word it..But cool, hopefully you will get things up and going, it is a really good radio hence the manual lol
